AUTOMATIC CAR-SIGNAL.

Specification of Letters Patent.

Patented June 8, 1915.

Application filed February 7, 1914. Serial No. 817,291.

To all whom it may concern Be it known that I, JOHN T. MOYER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Automatic Car-Signals, of which the following is a specification.

This device relates to railway signals and particularly to that class applied to street railway cars for notifying a person passing behind one car of the approach of a second car in the opposite direction upon an adjoining track.

The object is to provide such a device as will show a light or ring a bell on the rear of each of the two cars and operated by a simple apparatus which is fool-proof and not easily gotten out of adjustment.

Further objects and advantages appear in the specification when taken in connection with the accompanying drawings in detail.

Figure 1 is a plan view of the passing cars equipped with the invention; Fig. 2 is a vertical section of the cars showing the actuating mechanism; Fig. 3 is an enlarged detail view of the mechanism on one of the cars-that on the other being similar. Fig. 4: is a diagrammatic view of the preferred electrical circuit.

Referring to the drawings, cars A-and B are shown as passing in the direction of the arrows and are provided upon their upper adjacent edges with the improved device A and. B which actuates the respective lights A B" or bells A B at the time that the forward ends of the cars are opposite each other transversely of the tracks.

The actuating device comprises a stand ard 5 secured to the side of the car and extending upwardly, upon the free end of which is an enlarged head 6, connected to said car also by a brace 7, while journaled through said head is the central section of a reversely bent rocker comprising a rod 8, weight 9, and U-shaped upper end 10.

Through the upper end 10 passes slidably the slender end 11 of a vane 12 pivotally five cents each, by addressing the carried in the upper end of said head 6 by a bolt 13 and secured in position by a rivet 14 to swing in a horizontal plane. Upon opposite sides of said head are yielding spring contacts 15 insulated from their support by blocks of suitable material 16.

In wiring up the various conductors of the circuit the trolley pole 18 is connected through a resistance 19 to both of the springs 15 while the weight 9, through its grounded connection with the rest of the device, is connected to a switch 20 operative to connect with either of two contacts 21 and 22 for lighting a lamp 23 or ringing a bell 2% respectively. Finally the other sides of said light and bell are grounded to the car from which the device as a whole is insulated.

In the operation of the device it is assumed that two cars similarly equipped are passing and that as the respective vanes 12 contact and swing toward the rear of the respective cars the U-shaped arms 10 are swung forwardly, thus causing the lamp 23 to light or a bell 2a to ring as the switch 20 may be on either the point 21 or 22, respectively.

This constitutes the device comprising the preferred form of the invention but the applicant does not wish to be limited to its precise details, as his said invention anticipates any construction falling within the scope of the appended claim.

I claim In a device of the class described, a circuit closer comprising a vane pivoted for horizontal swinging movement, a weighted rocker pivoted for vertical swinging move ment and engaging one end portion of the vane, and a spring contact located in the path of movement of the rocker.

In testimony whereof I afiiX my signature in presence of two witnesses.

JOHN T. MOYER.
